Transport Stream Properties

Mux Parameters

Parameter nameDescriptionPossible values
Total Bitrate*Dimensions the bandwidth at multiplexer output. Embeds PSI and NULL bit rates, as well as the sum of the video/ audio/private stream bit rates embedded in multiplexer output.0 to 200000000 bps
Minimum Null Bitrate*Reserves NULL packet bandwidth. If component bitrate + null bitrate > total bitrate then component packets will be discarded0 to 200000000 bps
Transport Stream ID*Sets the Transport Stream ID in the output PAT, SDT and NIT (if enabled)0 to 65535
Original Network ID*Sets the Original Network ID in the output SDT and NIT (if enabled)0 to 65535
Source Redundancy ModeSee redundancy mode paragraph.Dropdown menu: Automatic no monitoring, Manual no monitoring, Automatic with monitoring, Manual with monitoring.
IP Active/StandbyEnable Active/Standby for IP outputTick box, disabled by default
Scramble transport stream packets containing a PES headerTS packets containing a PES header are scrambled if scrambling is required for the current service.Tick box, enabled by default

Mux Advanced Settings

These settings are only for advanced configurations. Default values should be suitable for the majority of use cases.

Parameter nameDescriptionPossible values
Input jitter buffer latencyThe latency on each input used to absorb input jitter. Requires a service restart to apply. Reducing this value can reduce the latency of the service in the multiplexing stage. However, depending on the service configuration (FEC and or RTP enabled) and on the input bitrate, reducing this value could lead to insufficient buffering available for the muxing process. In such case, an alarm will be raised to notify about possible problems in the output stream.10 to 30000 ms
Scrambling latencyThe added latency during which scrambling occurs.10 to 30000 ms
ASI Active/StandbyWhether ASI outputs should stop when in standby or not.Tick box
Copy SDT as SDT OtherControls which other transport streams will receive a copy of the SDTDropdown menu: To all networks, To same network, Do not copy
Hide transport streamHide this transport stream in the NIT included in other transport streams of the same DVB networkTick box

Output Parameters

Parameter nameDescriptionPossible values
Output Name*Used to identify the specific outputString of max 32 characters
TypeSelect the output typeDropdown menu: IP, ASI
Network interfaceName of network interface used for the output transport stream (as seen by the operating system)String of max 32 characters
Stream Address*Unicast or multicast destination IPv4 address for the Transport Stream packetsIPv4 address
Destination UDP port*Destination port for the Transport Stream packets0 to 65535
User-specified source detailsIf unticked, the output transport stream source IP address will be the IP address of the specified Network interface.
Otherwise, the source IP address field and source UDP port field of the output IP packet headers will be populated with the user-specified source IP address and source UDP port regardless of the IP address of the specified Network interface.
The specified Network interface will not respond to ARP or PING on a user-specified source IP address (unless the user-specified source IP address is the same as the specified Network interface).
If ticked, Source IP address and Source IP port field will be required (respectively, IPV4 address and value between 0 and 65535)
Time to liveSets the IPv4 Time To Live field (maximum number of routersa multicast packet can reach before being discarded)0 to 255
IP encapsulationType of IP encapsulation. E.g., FEC packets can be generated to protect the media packets.Dropdown menu: UDP, RTP, FEC
Server filterAssigned servers matching this patten will output using these settings. * = wildcard of any length. For example: s*1 would match 'server 1' and not 'server 2'String of max 32 characters
Output in the clearOutput all components in the clear. Overrides SCG config.Tick box, disabled by default

PSI SI Parameters

If the Enable or disable PSI SI tick box is enabled (default), it is possible to override the repetition rate (in ms) for any of the listed tables.

Bandwidth Policing Parameters

Use the Add Group button to add as many groups as needed.

Use the button on the right to remove a group.

For each added group, the following parameters will be required:

Parameter nameDescriptionPossible values
Name*Used to identify the specific bandwidth policing groupString of max 32 characters
BitrateMaximum bitrate allowed for the group. If the total bitrate of the components in the group exceeds this value, packets will be dropped and alarms raised.0 to Total Bitrate (as set in the Mux parameters)

TOT and NIT Properties

TOT

TOT: no configuration parameters available.

NIT

Parameter nameDescriptionPossible values
Network ID*Sets the Network ID used in the output NIT (if enabled)0 to 65535

Service Properties

Output parameters

Parameter nameDescriptionPossible values
NameA user-friendly name for the service. Note that this is not the Service Name, which must be configured via the Service Descriptor.String of max XX characters
Program Number*Program Number used to populate the output PMT and ServiceID in the SDT1 to 65535
PMT PID*Output PMT PID0 to 8190
Logical Channel NumberSets the Logical Channel Number in the NIT (if NIT is enabled and the Logical Channel Descriptor is present).
Values above 1023 are only allowed if the descriptor specifies the NorDig range.Leave blank if not required.
1 to 16383
PCR ComponentDropdown menu: Auto, Manually specified PID, None
Regenerate DescriptorDropdown menu: On, Off
Service PassthroughAutomatically add components and descriptors from the specified input service to this output service. If the specified input service cannot be found, there will not be an output PMT or PAT reference. This behaviour is dynamic and the output PAT/PMT references will track changes to the incoming service.Dropdown menu: Off, On
Input ProgramSpecifies the input Program Number to search for the incoming PMT in order to find the required input Service0 to 65535

If Service Passthrough is set to On, additional configuration parameters will be available:

Parameter nameDescriptionPossible values
Dropped PIDsComma separated list of PIDs which will not be passed through to the output service
Monitor health of all signalled input componentsHealth of all signalled components in source PSI/SI will be monitored. If Source redundancy mode is not manual, health failure of any of these components will result in a source switch if a healthy alternative is availableTick box, disabled by default
Bandwidth Policing GroupIf any Bandwidth Policing Group has been defined for the transport stream (see previous paragraph), the list of all group names will appear as a dropdown menu. Assign the service to one of the groups or leave the selection empty to avoid policing it.Dropdown menu: names of any defined bandwidth policing group.

Sources parameters

Define the parameters for the first input and then use the “+Add” Tab to define more other inputs.

For each input, new parameters can be configured manually or, if a source already exist, it can be shared between different inputs.

Note: It is recommended to add a User-defined name to the source to make it easily recognizable. The name will also be used to rename the tab.

Parameter nameDescriptionPossible values
User defined name for source*Name and also source tab name. This is the identifier of the current input which will also be used, when saving the configuration, to rename the current Source Tab.String of max 32 characters
